I would comment out:
I would un-comment:
iface eth0 inet static
and populate with the correct information. I would then do ifconfig eth5 down and ifconfig eth0 up.
If this doesn't work, I am out of ideas... If you still have problems, let me know and I will download an ISO and create a VM and see if I can get it resolved for you. If you need me to do this, please send me a link to download the specific version that you are using.
